The TUBE-TECH SMC2B is the Multiband Compressor that brings the full music back in your mix!

The possibility of combining sweet overall 3 band eq with individual compression of the three bands can make wonders for your mix, both for submix bus use ( drums, instrument groups or vocals ) but especially on the main mix.

SMC2B can also also be used to solve/ remove annoying frequencies in basses, vocals, etc. + It can even be set up as a d-esser.

SMC2B can be very effective when recording very dynamic vocalists without having to spend hours sorting out problems after the recording has been done.

The SMC2B is one of the few audio processors, hat is very hard to bypass, even after a short listening test, and it will tend to

stay inserted forever because of the color and dynamics it can add to your mixes.

These facts have made the SMC2B the favorite mixing/mastering compressor of many top mixers and mastering engineers around the world.

For Live use the SMC2B is also adding quality and musicality to top touring acts.

Try it for your own mixing, and hear the magic no other compressor can deliver!


Variable crossover points ensure precise control with all three bands of opto-compression. Independent band specific Threshold, Ratio, Attack, Release & Gain parameters make the SMC 2B as flexible as it is accurate.

The TUBE-TECH SMC 2B Stereo Multiband Compressor features three independent optical stereo compressors. The signal is divided into three bands (Low, Mid & High) by 6 dB/octave x-over networks with variable frequencies: 60-1200 Hz for Low/Mid band and 1,2-6 kHz for the Mid/High band.

The design of the x-over networks optimizes the summing of all three bands, resulting in a flat frequency response (within +/-0,25 dB), when the gain controls for each band are set at the same level. The three compressors feature Threshold, Ratio, Attack, Release and Gain and a display showing gain reduction. Master levels are set with Output Gain and Balance controls.

Both Input and Output are balanced and have fully floating transformers with a static screen. The power supply and the sidechain circuit is based on a solid state circuit. With the exception of the output stage all DC voltages are stabilised.

” I love my Tube Tech SMC2B and use it all the time!  Main use is for the mix bus compression.”

” Another great treat is the MMC1A for upright bass”

“I am Really Happy with it !!!!!!! It gives BALLS to every Mix.

Working light, it”s warming of the sound up and bringing the musicians acting together in the Mix.
Harder driven,there”s a real PUSH

….with Straight LO´s ,warm driving mids,and sparkling,clear,never annoying highs !!!!
vocals benefit from the warm,but never muddy mid´s.
The limiters after the SMC 2B has less stress, EQ`ing is easier than before ,

the complete analog chain works better.
Apart from of a technical limiter there is no more need for plugins.
Other plugins only used for repairs,effects ……since I have the TUBE-TECH SMC2B.
The Workflow is so much better & faster than before !!!!

A lot of knobs,but very easy to use.
So I like to say THANK YOU for this Very Cool Tool !!!!

“…….I use the Tubetech SMC2B on the mix buss on many occasions. I”ve used it on tracks for Rufus Wainright, Beck ,The All American Rejects, The Offspring. I love being able to have separate compression control over three bands. Often many stereo buss compressors will squish and darken the midrange of a track. In a rock track this takes the attack and impact out of the guitars and drums . Having the separate control over all parameters I can set my attack time to be the mildest on the electric guitar range. Being able to control the frequency range in the low end works well on tracks that are very dance oriented. I can adjust the crossover point and make sure the low end never gets to overcompressed and soft…… ”

“The SMC2B is an absolute favourite for mastering.”

John Webber, Blue Pro Mastering, London, UK

“I often use The SMC2B purely for it’s signal path and the tube and transformer combo seems to recue cold and brittle digital recordings. It’s also my go-to tool for tightening flabby bottom end.”
